Nexys2 Spartan3E-500 board - CY7C68013A

[Livia]

Hello,

does anyone know how is the CY7C68013A (USB Controller, EZ-USB) configured in the Digilent Nexys2 Spartan3E-500 board? I want to transfer data from a host PC to an FPGA via USB, through the CY7C68013A. However, this IC has a built-in CPU that configures its operation modes, and I have no idea of what the firmware is doing. The Reference Manual doesn't mention anything, and I need to know the configuration to be able to properly do the interface.

Thanks!

To give you a better idea of what I am trying to do, attached you will find a block diagram. It is a USB to VGA converter. I also need to know how exactly the data moves inside the CY7C68013A, from the USB host to the FIFOs... can't find this information in the datasheet neither in the application notes. Any help is appreciated.

Thanks.
